Checking Flywheel Pilot Bore Eccentricity(e)Measure the distance from the surface on thegenerator adapter that bolts to the engine flywheelhousing to the outside surface on the drive discs(Dimension "Y", figure 11-9). Then measure thedistance from the machined surface on the engineflywheel (Dimension "C", figure 11-10). If thedistance from the bellhousing to drive disc recess"C" is more than the distance from the generatoradapter to the drive discs "Y", install additionalspacers between the drive discs and the generatordrive hubs. If "Y" is more than "C", remove spacerslocated between the drive discs and generator hub.(f)Make certain drive discs "seat" in the drive discrecess.WARNINGNEVER GRIND OD OF DRIVE DISCSAND NEVER ATTEMPT TO "DRILLOUT" HOLES IN DRIVE DISCS. IFDRIVE DISCS DO NOT FIT PROPERLY,REPLACE DRIVE DISCS.(3)Locating Generator. Lift the generator by attachingan overhead hoist and slings to the eyebolts on thegenerator frame.11-16
